characterized by axially symmetric polarization and helical phase front, possess the unique …

An overview of the recent developments in the field of cylindrical vector beams is provided.
As one class of spatially variant polarization, cylindrical vector beams are the axially …

Optical vortex beams, possessing spatial polarization or phase singularities, have intriguing
properties such as the ability to yield super-resolved spots under focussing, and the ability to …

Vector beams have the defining property of nonseparable spatial and polarization degrees
of freedom and are now routinely generated in the laboratory and used in a myriad of …

Super-resolution optical microscopy, which gives access to finer details of objects, is highly
